DWL-900AP+ External Mounting Environmentals ;-((

[Brenton Hooper]

With the whole voltage drop over distance on cat5, why not just run some
2mill twin/figure 8?  This stuff is cheap as chips (got any sparky mates?
He'll probably give ya some for free), and all that extra copper should give
you a lot more range before having to worry about voltage drop problems.



Thx,
Brenton
